Abstract
Promotors for a crosslinking reaction involved in the curing of a system comprising crosslinkable polymers are bound to polymeric microparticles having a diameter of about 0.01 to 6 microns prepared by polymerizing a mixture of ethylenically unsaturated monomers. The microparticles carrying the crosslinking reaction promotor may be incorporated to coating compositions, printing inks, sealants, adhesives and other polymeric products in place of conventional crosslinking reaction promotors.
